Our vocabulary quiz cards for learning the definition of everyday math words.
| Question | Answer |
|---|---|
| Standard Notation | Just the number as we normally write it. |
| Equivalent | Equal in value but in different forms. |
| Whole Numbers | The number (0,1,2,3,....). There is no fractional or decimal part and no negatives. |
| Expanded Notation | Writing a number to show the value of each digit. It is shown as a sum of each digit multiplied by its matching place value (units, tens, hundreds, etc.) |
| Exponential Notation | A shorthand way of representing repeated multiplication of the same factor. |
| Scientific Notation | Where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit), Followed by: x10 to a power that would put the decimal point back where it should be. |
| Integer | A number with no fractional part. For example, -2, -1, 0, 1, 2 |
| Prime Factorization | A number, expressed as a product of prime factors. For example, of 24 is 2 x 2 x 2x 3. |
| Decimal | A fraction that that has a denominator of a power of ten, the power depending on or deciding the decimal place. |
| Positive Number | Numbers greater than 0 that can be written as a fraction or a terminating or repeating decimal. |
| Negative Number | A number less than 0; a number to the left of zero on the horizontal number line. |
| Array | A rectangular arrangement of objects in rows and columns. |
| Fractions | A number in the form a-b or a/b, where a and b are whole numbers and b is not 0. They are used to name part of a whole object or a part of a whole collection of objects, or to compare two quantities. They can also represent division. |
| Percents | Per hundred, or out of a hundred. For example "48% the students in the school are boys" that means that out of 100 students in the school, 48 are boys. |
| Common Denominator | Two fractions is any nonzero number that is a multiple of the denominators of both fractions. |
| Sum | The answer in an addition problem. |
| Least Common Denominator | The least common multiple of the denominators of every fraction in a given set. |
| Place Value | Determines the value of a digit in a number, written in standard notation, as determined by its position. Each place has a value ten times that of the place to its right and one-tenth the value of the place to its left. |
| Simplest Form | A fraction in which the numerator and denominator have no common factor except 1 and the numerator is less than the denominator. |
| Difference | The answer in a division problem. |
| Numerator | In a whole divided into a number of equal parts, the number of equal parts being considered or discussed. The number or variable on the top of the fraction. |
| Equivalent Fractions | Fractions that have different numerators and denominators but name the same value or number. |
| Denominator | The number of equal parts into which the whole (or ONE or unit) is divided. The number or variable on the bottom of the fraction. |
| Greatest Common Factor | The highest number that divides exactly into two or more numbers. |
| Least Common Multiple | The smallest number that is a multiple of two or more numbers. |
| Multiple | The result of multiplying by a whole number. For example 20 is a multiple of 4 and 5. |
| Exponent | A symbol or number placed above and after another symbol or number to denote the power to which the latter is to be raised. |
| Absolute Value | The absolute value of a positive number is the number itself. |
| Compatible Numbers | Numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally. |
| Front-End Estimation | Estimating to the highest place value. Ex. 7,438=7,000. |
| Round | This means reducing the digits in a number while trying to keep it's value similiar. |
| Prime Number | This is a number that can be divided evenly by only 1 or itself. It must be greater than one. |
| Estimate | A calculation of a close, rather than exact, answer; a "ballpark" answer; a number close to another number. |
| Composite Number | This is a number that can be divided evenly by numbers other than one or itself. It has more than one factor pair. |
| Factor | Factors are the numbers you multiply together to get another number. For example: 3 and 4 are factors of 12 because 3x4=12. |
